Design Of Positioning And Navigation Hand-held Terminal Based On WinCE

With the development of embedded system and communication protocol standards,indoor positioning technology becomes lower cost and more accuracy,many research centers and companies have pay their attention to it.At the same time,as the Internet of Things conception comes out,many network communication solutions such as wireless sensor network have been used in indoor positioning.Based on this underground,this paper has designed a Positioning and Navigation Hand-held Terminal based on WinCE,providing a comprehensive solution for Internet of Things and indoor positioning.This paper focuses on the Positioning and Navigation Hand-held Terminal hardware design,including the circuit of S3C6410 core,power management and communication modules.The paper also discourses the PCB electromagnetic compatibility design and simulation of the antenna.Because of being operating on Windows CE 6.0,this paper describes the system framework and the process of drivers,especially analyzing the backlight driver,WLAN driver and power management driver customization.At the end,this paper tests and verifies the system indoor positioning capability.
